In a bowl, combine the flour, sugar, baking powder, baking soda, and salt. Set aside.

In a separate bowl combine the half-an-half, egg, butter and syrup. Mix the liquid mixture into the flour and stir well to combine. Stir for 2 minutes to get rid of the lumps. Stir in the vinegar just until combines.

Cook in a hot nonstick pan over medium heat until dark golden and easy to get the spatula under to flip. Cook on the other side until done.
